Physics
How the physical world really works, in plain language - motion, energy, light, and the genuinely strange rules of the quantum world. The 'why' beneath the machine.
Basic
What Physics Actually Is Physics is the craft of predicting the world with simple models: measurement, units, and the idea that a few rules explain enormous amounts.
Energy, Forces, and Motion Newton without the dread: what a force really is, why things keep moving, and energy as the currency that is never created or destroyed.
Light, Waves, and Fields Why light, radio, sound, and ripples on a pond are the same idea: waves and fields, the electromagnetic spectrum, and what color really is.
Intermediate
The Quantum World, for Humans What is actually true about the quantum world, minus the mysticism: superposition, uncertainty, and entanglement, explained without lying to you.
Relativity: Space, Time, and Gravity Why moving clocks run slow and gravity is curved spacetime, in plain language - special and general relativity, with GPS as the everyday proof.
Heat, Energy, and Entropy The laws of thermodynamics without the dread - energy is conserved, entropy always grows, and that one-way arrow explains heat engines, perpetual-motion failure, and the direction of time.
Quantum Computing, for Humans What a quantum computer really is and is not - qubits, superposition, and interference used to make right answers likelier, not a magic box that tries all answers at once.
Advanced
The Physics of Computation A bit is a physical thing, not an abstraction - and that fact sets hard, measured limits on every computer that will ever exist, from your laptop to whatever comes after silicon.
